Firstly, don't forget to call your Dad today (assuming you are lucky enough to have a dad) even if, like me, you have a seriously busy day ahead of you!!
Secondly, spare a thought today for the Dads (and mums too) who support your work. I know that most of the projects I run would fall apart without parents supporting them. Parents bring their kids along. They convince the rest of the parish that what you are doing is worthwhile, and they help you out in all sorts of other ways too.
